Concentrated sulfuric acid (H₂SO₄) is solid as an 18 mol/L solution. A company uses this concentrated solution to prepare 2.0 L bottles of 1.0 mol/L sulfuric acid. How many 2.0 L bottles can be prepared from each litre of concentrated solution?

What is the mass of Na₂CO₃ required to make a 500 mL standard solution of 0.400 mol/L Na₂CO₃?

What is the molar concentration of a saturated CuSO₄.5H₂O solution that contains 20 g of solute in 100 g of water at 20⁰C? (Assume that 1 g of water gives 1 mL of solution.)

A cleaning product distributor has a warehouse storing 180 containers of oven-cleaning solution. The volume of each container is 25.0 L and the concentration of sodium hydroxide (NaOH) in each is 1.65 mol/L. What is the total mass of NaOH in the container?

The HCl solution shown is a commercially available standard solution. The 2.50 L container has a concentration of 1.00 mol/L. What is the concentration of the solution in units of %(w/v)?
